AL235 Position counter overflow warning
Checking method
and corrective action
5.
When AL060 and AL062 occur, use the scope to check if the feedback
position has overflowed. And check whether the above situations have
occurred, then establish the absolute origin coordinates.
How to clear the
alarm?
Incremental system: perform homing procedure.
Absolute system: establish the absolute origin coordinates.
AL237 Indexing coordinate is undefined
Trigger condition
and cause
Condition: the starting point of the indexing coordinate is not defined before
operating the indexing function and executing the indexing positioning command.
Cause: the servo drive cannot identify this coordinate system.
Checking method
and corrective action
Check if the indexing coordinate has been defined:
1.
Perform the homing procedure before using the indexing function.
2.
After this alarm occurs, use DI.ARST or set P0.001 to 0 to clear the alarm.
3.
This alarm is also cleared when you power on the servo.
How to clear the
alarm?
DI.ARST or set P0.001 to 0.
AL249 PR number exceeds the range
Trigger condition
and cause
Condition: the triggered PR path number exceeds the upper limit.
Condition: the triggered PR path number exceeds 99.
Checking method
and corrective action
1.
Check if the PR command jumps to a path exceeding the range.
2.
Check if the PR command format is correct.
How to clear the
alarm?
DI.ARST or cycle power on the servo drive.
AL283 Software positive limit
Trigger condition
and cause
Condition: the target position specified by the command exceeds the software
positive limit.
Cause: the software positive limit is triggered.
Checking method
and corrective action
The software positive limit is determined by the Position command instead of the
actual feedback position because the command is sent before the feedback is
received. That is, the actual position may not have exceeded the limit when this limit
protection is enabled. Set the appropriate deceleration time to achieve the desired
effect. For more information, refer to the descriptions of P5.003.
How to clear the
alarm?
The alarm is automatically cleared after moving away from the limit.
